Description

We reported depletion spectra of Rb2+ complexed with up to ten Helium atoms. The ions were formed by doping helium nanodroplets in a pickup cell filled with low-density Rb vapor and subsequent electron ionization. Two absorption bands were observed between 920 and 250 nm, due to transitions into the 12Σu+ and 12Πu states. The transitions are blue- and redshifted, respectively, when the number of He atoms is increased. Spectroscopic constants and the spin–orbit (SO) splitting are deduced for the bound 12Πu state. All experimental findings are supported by ab initio calculations, using CCSD method for modeling ground electronic state, and EOMCCSD and MRCI for electronically excited states.
